Patent SE-157330-C1 (SE)
IPC: B01J47/00
Filed: 1954-01-29
Abstract: Betaine and glutamic acid are obtained from molasses by the addition of one or more organic diluents, followed by or simultaneously with an acid whose salts with the cations present in the molasses are difficultly soluble or insoluble in the liquid medium, the precipitate is separated, the organic diluent evaporated, and the remaining liquid passed through one or more ion exchangers.  The first is anionic and glutamic and pyrrolidone-carboxylic acid are retained; the second is cationic and holds betaine.  Organic diluents are methyl and ethyl alcohol and acetone; whilst acids are sulphuric, sulphurous and phosphoric.  Specification 744,114 is referred to.ALSO:Molasses is diluted with one or more organic liquids miscible therewith, an acid is added, either separately or with the organic diluent, whose salts with the cations present in the molasses are difficultly soluble or insoluble in the liquid medium, the precipitate is separated, the organic diluent evaporated, and the remaining liquid passed through one or more ion exchangers.  The first exchanger is anionic and this holds the acids, whilst the second exchanger is cationic and this holds the betaine. Specified diluents are methyl alcohol, dilute ethyl alcohol and dilute acetone, whilst acids specified are sulphuric, sulphurous and phosphoric. Amounts added are-diluent, 0,6-2 kg. per kg. molasses; acid-to give a pH of 2-3,5.  The precipitate may be formed at elevated temperatures, or after formation, be heated to such temperatures e.g. 35 DEG -80 DEG C.  After precipitate removal sugar may first be recovered as described in Specification 744,114, but sugar may also be obtained from the syrup obtained from the liquid after its passage through the final exchanger.

Title: Hydrodynamic coupling
Inventor: ADAMS WERNER
IPC: F16D33/06
Filed: 1982-08-24
Granted: 1984-05-24
Abstract: In a hydrodynamic coupling with a primary blade wheel 13 and a secondary blade wheel 12 which together define a working space 9, there is within the blading of the primary wheel 13 a blade-free reservoir 25 which can take up part of the working fluid from the secondary blade wheel 12 in the event of high slip. A delay chamber 18 separated from the reservoir 25 by a dividing wall 22 is connected to the working space 9 via channels 28, 29. A restriction plate 24 is provided in the flow path of the working fluid from the secondary wheel 12 to the reservoir 25. The dividing wall 22 has a collar 23 which delimits the reservoir from the blade channels of the primary wheel 13 and is arranged in such a way that the axial length e of the reservoir is at most 30% of the axial depth b of the blade channels of the primary wheel 13. The restriction plate 24 is situated in the centre plane E of the coupling, with the result that the axial clearance a between the collar 23 and the restriction plate 24 is only about 5 to 10% of the axial depth b of the primary blading (Figure 1).

Title: Pipe-rotating mechanism for pneumatic stowing lines
Inventor: PAWELSKI LUDWIG
IPC: E21F15/08
Filed: 1986-08-09
Granted: 1988-02-18
Abstract: In a pneumatic stowing line with which the waste in underground coal mining is conveyed into the worked space, the requisite zonal dismantling of the pneumatic pipe bend in the face/roadway transition area involves substantially reduced idle time and is ergonomically more favourable owing to the fact that a mating pipe is arranged in front of the pneumatic pipe bend, which mating pipe has a rotatable pipe connection and is acted upon by a pipe-rotating mechanism via which the pneumatic pipe bend can be swung into the roadway after separation of the coupling from the face line. After the swivelling operation, the line laid in the roadway is then pushed into the new position via telescopic devices, whereupon the pneumatic pipe bend can then be swung back into its initial position and attached to the correspondingly displaced line laid at the face. The rotating mechanism has a lifting piston, the horizontal movement of which is converted via a coarse-thread shaft into a rotary movement, in the course of which a toothed disc sitting on the free end of the coarse-thread shaft is in engagement with rack elements which are fastened to the rotatable section of the mating pipe. <IMAGE>

Granted: 1993-04-08
Abstract: An electronically controlled switching relay is proposed which comprises a measuring circuit, a control circuit, a device for setting a preselectable value of a measured variable, which has a potentiometer and a display element dependent on the potentiometer, and a display device which is provided with a scale and a moving pointer. The control circuit converts the analog setting signal, output by the potentiometer, of the preselectable value of the measured variable via an A/D converter into a digital signal, and compares an instantaneous value, prescribed by the measuring circuit, of the measured variable with the set preselectable value and outputs a signal in the event of equality. The display device has a plurality of radiation sources which are in each case driven by the control circuit as a function of the instantaneous value in such a way that they simulate a moving pointer. <IMAGE>
